Sewage backup cleanup in Mesquite

Why sewage is a different job

The IICRC S500 standard, which restoration providers follow, puts sewage and toilet backflow from beyond the trap in Category 3, grossly contaminated water, "regardless of visible content or color." It can carry bacteria, viruses and parasites. Anything porous it soaks into, including carpet, pad, drywall, insulation and particleboard cabinets, generally cannot be cleaned well enough to keep and is removed.

That changes everything about the cleanup: crews wear protective equipment, set up containment so contaminated debris does not get tracked through the house, and disinfect before they dry. Running a shop vacuum and a fan, which may be fine for a clean supply-line leak, can spread contamination with sewage.

Immediate safety steps

• Stop using all water in the house: no flushing, showers, laundry or dishwasher until the line is cleared.
• Keep children, pets and anyone with a weakened immune system away from the affected area.
• Do not touch sewage with bare skin. If you must enter, wear rubber boots, gloves and eye protection, and wash thoroughly afterward.
• If sewage is near outlets or appliances, turn off power at the breaker only if you can reach it from a dry spot.
• Close the doors to the affected rooms and, if possible, turn off the HVAC so air does not circulate through the area.
• Photograph everything before cleanup starts.

Call about a sewage backup

Common causes in the area

• Clogged lateral lines. Grease, wipes and paper products build up in the line between the house and the sewer main. The backup usually appears at the lowest drain, often a shower or tub.
• Root intrusion. Landscape trees and shrubs, especially in older neighborhoods, send roots into joints in clay or older pipe.
• Line damage and settling. Bellies or breaks in the line, sometimes found during slab leak repairs, collect debris until they block.
• Septic problems. Some rural properties in Bunkerville, Moapa Valley and the Arizona side rely on septic systems, which can back up when full or when the drain field fails.
• Storm and flood events. During the December 2010 Virgin River flood, a sewage plant overflow led the sheriff's office to warn residents about fecal matter in the floodwater. Flood water should always be treated as possibly containing sewage.

What sewage cleanup usually involves

1. Assessment of how far the sewage traveled, using moisture meters to find where it wicked into walls and under flooring.
2. Containment with plastic barriers and, on larger jobs, negative air pressure so contaminated air and dust stay in the work area.
3. Extraction of liquid and solid waste with dedicated equipment.
4. Removal and disposal of contaminated porous materials. Drywall is typically cut well above the wet line.
5. Cleaning and disinfection of the slab, framing and all hard surfaces.
6. Drying with dehumidifiers and air movers, with daily moisture readings.
7. Verification before rebuild. Some providers or owners order surface testing on larger losses.

Insurance for sewer backups

Sewer and drain backup is one of the most common surprises on a homeowners claim. Many standard policies exclude it unless the owner added a water backup endorsement, which often has its own limit. A backup caused by flooding from outside falls under flood insurance instead. Call the insurer early, describe the source accurately, and keep the plumber's invoice showing what caused the blockage. The Nevada Division of Insurance claim steps are summarized on the insurance guide.

Cost

Sewage cleanup costs more per square foot than a clean water loss because of the protective equipment, disposal and extra removal. Published cost guides put general biohazard cleanup in the range of about $1,500 to $5,000 for typical jobs, with large losses higher. A backup confined to one tiled bathroom is at the low end; one that reached carpeted bedrooms and hallway walls is not. See the cost guide.

Questions to ask the provider

• Will you treat this as Category 3, and what containment will you use?
• How will contaminated materials be disposed of?
• What is your Nevada contractor license number?
• Can you coordinate with a plumber to clear or camera the line?
• Will you document removed contents for my insurance claim?
